Performance & Attention To Detail

The industry's leading performance is about doing all of the little things right. And as anyone whose been in this business long enough will tell you, the little things make all the difference. Together with our customers, we've created the simplest machine for hydro excavating. And we've done it in a way that means the lowest long-term cost of ownership.

Everything You Need

Known throughout the industry as building the longest-lasting and most user-friendly hydro excavators, we’ve taken our 30 years of industrial vacuum experience and created the most reliable and most budget conscious excavator in its class. The GapVax VHE combines the best of both worlds: A severe-duty base model, combined with a comprehensive list of optional equipment that gets you exactly what you need, without paying for things you don’t.


Time Tested

The first thing you’ll notice is how similar our VHE and MC units appear. It’s not a coincidence. As the old saying goes, “If it aint broke, don’t fix it.” Basic features include: A full opening tailgate that provides unobstructed dumping and simple washout, A tailgate hinge and locks that are adjustable using two wrenches, An integral debris body and water tank that keeps the center of gravity lower to the ground, and ergonomic tool storage for easy access to regularly used items like vacuum tubes, hoses and water lances.

The Real Difference

Working on and maintaining a GapVax is where we really stand apart from the rest. Everything is easily accessible and easy to maintain—the pump, the cleanouts, the grease points, and kunkle valves. Everything is built to be maintained at the lowest possible long-term cost.


Right Where You Need It

GapVax trucks are designed with the operator in mind. So everything is easily accessible and right where you need it. We try to go the extra mile to save backs and joints– because, at the end of the day, the only thing more important to your fleet than your vacuum truck is the person operating it.

Ready for Winter

We know you can’t stop working just because the thermometer drops. We also understand the expenses related to costly equipment freeze-ups. That’s why we offer you options that safely winterize your VHE. From heated pump and tool storage, glycol and air-out systems, the GapVax VHE won’t leave you out in the cold during the winter months.


Big Legal Loads

Let’s face it, the rules and regulations for safe excavating increase each year. Its tough to stay compliant without breaking the bank, but the GapVax VHE will help carry the load without burying your budget. And you’ll still receive all the benefits synonymous with a GapVax: operator friendly design, lowest cost to maintain, unmatched fleet uptime, and best-in-class performance.
